Cannot print? Internet down? Windows Troubleshooting can automatically pinpoint and fix common problems, just so you do not suffer.
It's in Control Panel and equipped with more than a dozen troubleshooters for problems with networking, Internet, audio and video, and program compatibility. Windows Troubleshooting isn't designed to solve every issue, but it can often save you time and headaches.
It can also help head off trouble by providing basic scheduled maintenance, such as cleaning up temporary files or scanning your hard disk for errors. If something suspicious turns up, you'll get a notification in Action Center.
